. Podspec dependency problem handling

Encounter a situation ：

• I use RxSwift, however RxSwift stay github Upper Department , Sometimes the network is bad
• So I put RxSwift Pull me down Giee Warehouse , To facilitate better use
• stay profile Add... When using

  pod 'RxSwift',  :git=> 'https://gitee.com/tripartite/RxSwift.git',  :tag=> '6.5.0' 
  pod 'RxCocoa',  :git=> 'https://gitee.com/tripartite/RxSwift.git',  :tag=> '6.5.0'

however pod install The lack of time has encountered a problem , One by one RxSwift No problem , however RxCocoa Always report an error

[!] CocoaPods could not find compatible versions for pod "RxRelay":
  In Podfile:
    RxCocoa (from `https://gitee.com/tripartite/RxSwift.git`, tag `6.5.0`) was resolved to 6.5.0, which depends on
      RxRelay (= 6.5.0)

None of your spec sources contain a spec satisfying the dependency: `RxRelay (= 6.5.0)`. 

Problem cause analysis

RXSwift There are multiple under the original file .podspec

Here's the picture , There is a dependency between them , open RxCocoa.podspec, You find RxCocoa Need to rely on RxSwift and RxRelay

  s.dependency 'RxSwift', '6.5.0'
  s.dependency 'RxRelay', '6.5.0'

resolvent , Add dependency

Add dependency , then pod install , Problem solving

  pod 'RxSwift',  :git=> 'https://gitee.com/tripartite/RxSwift.git',  :tag=> '6.5.0'
  pod 'RxRelay',  :git=> 'https://gitee.com/tripartite/RxSwift.git',  :tag=> '6.5.0'
  pod 'RxCocoa',  :git=> 'https://gitee.com/tripartite/RxSwift.git',  :tag=> '6.5.0'
